FLASH Application led Hay 23,

My invention relates to ashlights, containing batteries enclosed in a casing, and it consists in the novel features, which are hereinafter more fully described.

One of the objects of my improvment is to reduce the number of parts of theflashlight, thereby reducing the cost of the same. Another object o'f -my improvement isto eliminate from the sides of flashlights. the lshifting -devices, which are employed for making and breaking the circuit of the ashlight.

A further object of m improvement isto preventthe accidenta closing of the cir-v 15 cuit in flashlights.

Anotherobject of my improvement isto eliminate :from the flashlight the lamp socket with the-internal thread in it.

Another object of my invention is-to provide'a ashlight with a spring, which has a part on it, which is so constructed as to engage a screw-thread on the stem of a suitabie lamp of said ashliglit and to'replace a socket with an internal thread therein.

Another object of my invention is to make the reflector ofthe flashlight integral Fig. 4 is a flashlight spring, which I provide.

Like numerals refer to' like parts throughout the several views. l f

V11v designates the lower part of the flash-l light casing, which has-'therein an opening 12 at the lower en d thereof, for a purpose, which is hereinafter described.

A disc 13 is shownas enclosed -by said part 11 and is positioned at thelower end thereof near said opening 12.

Batteries

14 and 15 are show'n as placed in with detail in elevation of the special contact tween `sa1d maar.

19a?. serial No; 193,547.'

said part 11, normally resting on said disc 13 and kept in contact therewith by means of a spring 22, which is hereinafter-describedmore iny detail. Y

An upper part 16 of the flashlight casing is detachably .mounted on said part 11, as shown in Fig. 1 ofthe drawings, and may bev connected thereto by mea-ns of a bayonet joint of standard shape and construction, or in any other suitable manner.

The said of a reentrant extension 17, which has at the `inner end thereof an opening 18 for the stem` 19 of a flashlight lampv 20, which may be` of standard construction.

art 16 is shown as having integrally t erewith a reflector in the' form 'fof' The stem 19 of said lamp 20 has thereonscrew threads 21,1which are shown as having a very large pitch, for the sake of clearness,

and is kept in position by means of. the' spring 22, which has thereon at the intermediate tp fit the groovesY between said threads 21;

these coils 23 are also shown as having an extra lar pitch.

part thereof one or more coils 23,

The ot er coils of said spring 22 are enlarged towards the ends thereof, as shown v in Figs. 1 and 4; the upperend of'saidv 22 is encompassing said reflector 1T and a utting against the upper end thereof,n`

inside of said part 16, as shown in'Fig. 1.

The lower end of said spring 22 is vshown as resting-on and abutting material is shown as inte against' the top of. said battery 15; a ring 27 of msulatng between the top' end of said battery 15 and the'lower end'of said sprin 22, to prevent a short circuit'between

sai batteries

14,and 15 and said parts 11 andl. h Y

Said

batteries

14 and 15 are also showxi'as Vencompassed by*a tube or wrapper 26 of insulating. material, and they when said disc 1 3- with theI

batteries

14 and 15 thereon are raised or pushed inward- 1y by the nr of the o rator ofthe Hashllght, exten g throng said opening 12,

against the force of sald spring 92, therebyclosing the circuit of the flashlight.

When the finger of the `operatoa is ref moved from the disc 13, the spring 22moves the

batteries

14 and 15 with the. disc 12 to their o al positon, thereby breaking the

spurs

24 and 25 and thereby opening the circuit of the flashlight.

ave thereon 25,` to be brought into contact with" -a at the lower end of said stem i9 lie ABy the above construction I eliminate the ca which is employed with standard flashlig ts and the socket with the female thread in it for supportin said stem 19.

I also elimmate e shifting devices, which are commonly employed on the sides of flashlights, for making and breaking the circuit and remove the possibilit of accidentally closing the circuit by brus ing against said shiftin devices. y v

By t e above construction I also provide a resilient connection' between the lamp and the reiiector of the flashlight, to prevent aecidental breaking of the lamp by impact, as

when drop ing the flashlight.

Many ot ier changes may be made in the design of my flashlight without departing from the main scope of my invention, and parts of my inventlon may be used without other parts.

I do not, therefore, restrict myself to the details as shown in the drawings; butI intend to' include also all mechanical equivaylents` and obvious modifications of the same within the scope of my invention.

I claim as my invention and desire 'to secure by Letters Patent:

1. In a {iashlight a casing, enclosing batteries and comprising an upper part and a ao lower part, a lamp, a' threaded stem thereon,

an opening in said upper part, for said stem to pass therethrough, and a spring, for separating said'batteries from said stem, said spring having thereon one or more coils, to fit between the threads on said stem, there- Aby keeping said lamp in position.

2. In a flashlight a casing, enclosing batteries and comprising a lower part and an thereon an end in abutment with said upper l part, another end in abutment with said batteries and an intermediate part, to lit between the threads on said stem, thereby keeping said lamp in position.

3. In a flashlight a casing, to enclose batteries, an upper part thereon, a refieetor, made integral with said part, a lamp, a threaded stem thereon, an opening in said upper part, for said stem to pass therethrough, and a spring for separating said batteries from said stem, said spring having l thereon one or more coils, to fit between the threads on said stem, thereby keeping said lamp in position.
